MR-based electrical properties tomography converts the MRI transmit/receive RF field measurements to tissue electrical property maps through dedicated reconstruction algorithms. Recent reports showed that despite limitations, electrical properties tomography holds promise for generating additional contrast for tumor detection and patient-specific modeling of tissue-RF field interactions. This review summarizes the available tissue electrical property contrasts and compares them with the capabilities of the most commonly used electrical properties tomography reconstruction method. Future directions and prospects of clinical translation are discussed.
基于磁共振的电阻抗成像通过专用的重建算法,将 MRI 发射/接收射频场测量值转换为组织电阻抗图。最近的报告表明,尽管存在局限性,但电阻抗成像在生成肿瘤检测的额外对比度和组织-RF 场相互作用的患者特异性建模方面具有广阔的应用前景。本综述总结了现有的组织电阻抗对比度,并将其与最常用的电阻抗成像重建方法的能力进行了比较。讨论了临床转化的未来方向和前景。
